Description
Technical field
The present invention relates to electronic information fields, control chip more particularly to a kind of flash memory.
Background technique
Flash memory (Flash Memory, abbreviation flash) is that a kind of the non-volatile of long-life (remains to protect under power blackout situation
Hold stored data information) memory, data deletion be not as unit of single byte but be with fixed block
Unit,
With the appearance of the new model flash memory of more and more deep submicron process, booster circuit inside flash at
For part more and more fragile in flash, the ratio for the case where full wafer flash caused by it goes wrong can not work
Also higher and higher, and as flash uses the increase of time, the output voltage for increasing booster circuit prolongs the flash service life
With very direct effect, but changeless output voltage will lead to the service life of more and more flash units inside flash
It terminates in advance.
Summary of the invention
In view of this, the main purpose of the present invention is to provide a kind of flash memories to control chip, core can be controlled with secondary flash
Piece realizes boosting.
To achieve the above object, the present invention provides a kind of flash memories to control chip, comprising:
Auxiliary boost circuit module, the use duration for controlling chip according to flash memory adjust described in determining be provided to
Flash memory controls the target voltage values of chip, and the use of itself output voltage is that flash memory controls chip liter according to the target voltage values
Pressure.Preferably, the auxiliary boost circuit module includes:
Initial output voltage value determines submodule, needs to control the initial output that chip provides for the flash memory for determining
Voltage value；
Output voltage values adjusting submodule, the use duration for controlling chip according to the flash memory adjust described initial defeated
Voltage out obtains needing to control the target output voltage that chip provides for the flash memory；
Boost submodule, for the use of the target output voltage being that flash memory control chip boosts.
Using a kind of flash memory control chip provided by the invention, including auxiliary boost circuit module, auxiliary boost circuit mould
Block determines the target voltage for being provided to the flash memory control chip for controlling adjusting using duration for chip according to flash memory
Value, and the use of itself output voltage is that flash memory controls chip boosting according to the target voltage values, chip, which is controlled, for flash memory increases
Auxiliary boost circuit prevents the booster circuit failure of flash memory control chip interior from flash memory being caused to control chip failure, increases
The service life of flash memory control chip.
Detailed description of the invention

Output voltage values；
Output voltage values adjusting submodule 202 determines that submodule 201 is connected with the initial output voltage, is used for root
The initial output voltage is adjusted according to the use duration of flash memory control chip, obtains needing to control chip for the flash memory mentioning
The target output voltage of confession；
Boost submodule 203, is connected with the output voltage values adjusting submodule 202, for defeated using the target
Voltage is that the flash memory controls chip boosting out.
Flash memory control chip has been grown erasing times using the time and has been increased, and has respective record, auxiliary boost circuit in the chips
Module can control the use duration dynamic adjustment and boosted output voltages value of chip with the flash memory of record, equal using loss
It accounts method and adjusts determining output voltage values.
Using a kind of flash memory control chip provided in this embodiment, including auxiliary boost circuit module, for according to target
Voltage value is that flash memory controls chip boosting using itself output voltage, controls chip for flash memory and increases auxiliary boost circuit, prevents
Only the booster circuit failure of flash memory control chip interior causes flash memory to control chip failure, and auxiliary boost circuit module can be with
Chip is controlled according to flash memory and dynamically adjusts itself output voltage values using being continuously increased for time, increases flash memory control chip
Service life,
It should be noted that all the embodiments in this specification are described in a progressive manner, each embodiment weight
Point explanation is the difference from other embodiments, and the same or similar parts between the embodiments can be referred to each other.
For system class embodiment, since it is basically similar to the method embodiment, so being described relatively simple, related place ginseng
